Particle Image Velocimetry

Instantaneous Velocity Vector Maps

The fluid is seeded with micron sized tracer particles which follow the flow dynamics. These particles are then illuminated via a pulsed laser so that the particles are visible. The motion of the particles between two light pulses is captured via a CCD camera and processed to calculate the displacement and velocity of the flow being investigated.

This method is non-intrusive and can produce two dimensional or even three dimensional vector fields.
